What is the current behavior?

When using SQL and calling GET /clients/nonexistingclient or using cli hydra clients get nonexistingclient, the endpoint return 500, while it should return 404. In memory mode, the behaviour seems to be correct.

SQL:

{
    "error": {
        "code": 500,
        "message": "Unable to find client adfadf"
    }
}

Memory:

{
    "error": {
        "code": 404,
        "message": ": Not found"
    }
}

Which version of the software is affected?

v1.0.0-beta.2
